i-Strength Leg Curl/Leg Extension

A smart dual-function leg extension and leg curl machine for efficient quad and hamstring training in commercial strength facilities.

The Spirit i-Strength Leg Curl/Leg Extension is designed for facilities that want high-value lower-body training without wasting floor space. It challenges the quadriceps and hamstrings from one seated position, allowing users to switch exercises and adjust the setup without leaving the machine.

The machine's axis of rotation is optimized for a natural feel across both movements, while the i-Strength mechanical resistance system keeps every rep smooth and controlled. With digital resistance and multiple training modes, it is a strong fit for commercial gyms, rehab environments, hotels, estates and corporate wellness spaces.
